Power Expander Eq10 - 9/2/2007 6:23:49 PM

Status: offline 		I am assembling a 132" AC-130U. I was looking at purchasing the Power Expander Pro, then I read about the Eq10. After reading both available PDF user's guides, I still have a lingering question.

If I go with the PRO version, I am going to purchase the Turbo Regulator.

After reading about the Eq10, does this have a built in dual battery regulator, as long as it between 5.5-8.5v? I havent decided on LiPo of Lithium Ion batteries. Regardless of the battery selection, I need to get a power expander installed shortly.

If I go with the Eq10, will I only need the additional Pin/Flag failsafe, or will I need slider switches also?

Any help is appreciated.
Mike

Status: offline 		Hi Mike,
The Eq10 is just like the Pro except for the servo matching. If you plan on running lithium batteries you need to use a TurboReg with either one. The Pin & Flag failsafe switch (order the Failsafe Switch and Charge Package) would be used with the TurboReg in either case also. You would not also need slide switches. The one small drawback of a failsafe switch is that it draws a very small amount of current even when off. Its about 5mAH/Day out of each pack. For this reason we recommend disconnecting your batteries when you are going to have the plane sit a week or longer. If you want to avoid this issue then you would want the SuperSwitchHD 2Pak and would not need the failsafe swtich.
Please let me know if you have any other questions.

You cannot use the charge ports for powering the unit. They can only handle a couple amps each. You have to use the Deans plug inputs. Maybe I misunderstood your question. I was not really clear on what you were asking. Please let me know.

I know the EQ10 has servos matching on 10 channels but could you explain how do you plug 3 servos/ailerons? Could i set different servo throw on all 3 servos if they are connected on the same channel?

Status: offline 		Hi Daniel,
Each servo on each channel can have its center and endpoints individually set to match all the servos on a single channel. I don't know if you have ever used a Matchbox but the Eq10 is like having 10 Matchboxes (actually Equalizers), one for each channel. Please let me know if you need more information.

Status: offline 		I red in this thread that you need to use a turbo reg with the EQ10, when using lithium, however, the conntction schematics shows the lithium batteries connected directly. On the web page next to the manuals, it dose say that you need to use the regulator with the lithium. Im assuming the diagram means 2 cell Lithium 8.4 v max. Are we saying that the diagram is incorrect? This is the same diagram that came with the regulator. I was thinking about removing my turbo reg.

Status: offline 		Hi,
You "can" connect lithium batteries directly to the PowerExpander BUT you have to have servos that can take 8.4V. Most servos can't and most servos trash the gears much, much faster at that higher voltage even if they can take the voltage. This is up to you but if you pop a gear train and the servo freezes in flight I warned you. Most servos are recommended to run at 6.0V so a SuperReg (100cc) or a TurboReg (150cc) is recommended to regulate the voltage down to the voltage most servos are rated at.

Status: offline 		Ok, I understand, there is no regulator in the expander, so the voltage just passes through, so my turbo regulator will stay in my 42 % Thanks for the info. Probably could have answered my own question if I red the specificaitons, lol.

Status: offline 		Hi Robert I just read a post that the EQ10 will not work with the new JR12X. Apparently it won't reverse a servo. Only from the TX. I have 2 EQ10's and have a 12X on order. Do you know if they are compatible? If not I will cancel the JR because I think the EQ is invaluable. Eric

Status: offline 		HI Eric,
Where did you read that post? Reversing a servo on the Eq10 has nothing to do with the receiver. it will reverse a servo no matter what receiver is plugged in. I have not gotten my hands on a JR12x, but I see no reason it would not work. We work with all the new Futaba receivers. I doubt seriously I would get any special treatment if I asked JR for an early one.

Status: offline 		Hi Eric,
I had a friend help me find it, thanks. I am not sure what they mean. If you reverse a servo on the Eq10 it will go in the opposite direction the transmitter commands it no matter what. There is no way around this. I have asked the poster to contact me and explain his assertion in more detail. I do know on the AR7000 we discovered that if you reverse the throttle servo after binding it does not reverse the failsafe position. This bit one guy.

Status: offline 		Hi Eric,
I am not sure what you mean by confirm it. I have no idea when I will get my hands on a 12X. I know the way the Eq10 works and it will always reverse a servo if it is set to.
